Since Mbappe joined Real Madrid he even had better performance than we could expect to see from this player.
Simply if you compare Ronaldo with Mbappe when they joined Real Madrid you can understand the performance of Mbappe as even better than Ronaldo.
When Ronaldo joined Real Madrid he could only score 13 goals for this team while Mbapep scored 14 goals which meant he scored one more goal.
Mbappe warmed up worse than Cristiano Ronaldo in Real Madrid, but assess their performances and achievements in Real Madrid will need more time, matches and seasons from Mbappe. Only look at several matches and say this player is better than another player, can be very inaccurate by lacking enough performances. Players can play very well or very bad in several matches but in long term, their success will be assessed by quality and consistency.
Apart from that, I personally think Mbappe's current performance is good, but not yet at a stage that could be said to be extraordinary. Because currently what I see is that Mbappe is still in the adjustment phase to his current new position. So we can conclude, if for example Mbappe was able to adapt perfectly to Real Madrid, he would definitely be able to produce a much better performance than he is currently doing.
His performances become better with time, and I thought about it two months ago too. Luckily Mbappe did not get serious injuries and this helps him to adapt well in Real Madrid with time. With a skillful and clever player like Mbappe, if he has good fitness, he will play well after having good adaptation in a new club.
Maybe according to my predictions, next season Mbappe will be able to produce his best performance which will definitely make Real Madrid even greater. So hopefully Mbappe's adaptation process can run smoothly at Real Madrid so he can really become a really great goal scoring machine.
I think about it too, as after first warm-up season, and build up good connections with his teammates, Mbappe will perform better in a next season. Real Madrid have a good squad to move in future with many young, talented, and also experienced players. Players like Mbappe, Vinicius, Rodrygo, Jude are young but they are very experienced.
